Description

Technical Field

[0001] This invention relates to the field of ceramic tile processing technology, specifically to a processing and leveling mechanism for textured ceramic tiles. Background Technology

[0002] The processing of tiles with special patterns requires machining the patterns onto the blank body during the semi-finished product sampling process. The main difference between tiles with different patterns lies in the scraper (roller-shaped) of the leveling machine. The leveling process is a key step in ensuring the surface precision and three-dimensionality of the patterns on the tiles. However, existing processing equipment has many technical pain points, the specific problems of which are as follows:

[0003] The scraper assembly is heavy and has high energy consumption and poor rotational stability: Traditional tile scraper assemblies mostly use solid metal cylinders as the scraping carrier, which usually weigh more than 20kg. Not only do they require a high-power drive motor (power ≥1.5kW) to drive them to rotate, resulting in high energy consumption, but also due to their heavy weight, they are prone to vibration when rotating, resulting in low scraping accuracy (error ≥0.2mm) and inability to guarantee the regularity of the grooves.

[0004] If a hollow cylinder structure is used to reduce the weight of the scraper assembly, the existing support methods (such as rigid shaft support at both ends) cannot provide uniform radial support. The hollow cylinder is prone to deformation under the action of rotational centrifugal force and scraping load, resulting in the deviation of the scraping trajectory and the problem of scraping too deep or too shallow on one side. Therefore, the hollow lightweight design is difficult to implement in actual production.

[0005] Traditional equipment requires repeated manual calibration (taking ≥30 minutes per cycle) to center the scraper assembly, and the positioning accuracy is greatly affected by manual operation (coaxiality error ≥0.5mm), resulting in poor consistency of the pattern of tiles within the same batch and a defect rate of over 5%. When the scraper blade wears out or needs to be adapted to tiles with different patterns, multiple sets of bolts (usually 8-12) must be removed to replace the scraper assembly, a process that takes ≥30 minutes and requires specialized tools and personnel, resulting in long downtime and severely impacting the continuous operation efficiency of the production line. Therefore, we have introduced a scraping mechanism for processing textured tiles. Summary of the Invention

[0006] The purpose of this invention is to provide a processing and leveling mechanism for textured ceramic tiles to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A processing and leveling mechanism for textured ceramic tiles includes a base. The upper end of the base is provided with two sets of U-shaped supports that are symmetrically arranged front and back. A hollow leveling component is provided between the two sets of U-shaped supports. A connecting support component is symmetrically arranged inside the hollow leveling component. The U-shaped supports are provided with a quick-release connecting component that can be raised and lowered. The connecting rod of the connecting support component extends out of the hollow leveling component and connects with the quick-release connecting component.

[0009] When the hollow leveling component is placed on the quick-release connecting component, the quick-release connecting component tightens the connecting rod under the weight of the hollow leveling component itself, so that the inner end of the connecting support component is supported on the inner wall of the hollow leveling component, and the hollow leveling component is centered between the two sets of U-shaped supports.

[0010] Preferably, the hollow leveling assembly includes a lightweight hollow cylinder, a raised scraper on the surface of the lightweight hollow cylinder, an annular end caps fixed at both ends of the lightweight hollow cylinder with countersunk screws, and an intermediate cylinder centrally connected to the inner end of the annular end caps, the intermediate cylinder extending into the lightweight hollow cylinder.

[0011] Preferably, the connecting support assembly includes a bushing rotatably connected inside the intermediate cylinder, a movable cylinder integrally formed on the connecting rod, a hollow plug screwed to the inner end of the bushing, first push rods evenly spaced on the inner end of the connecting rod, and a roller movably connected to one end of the first push rod extending out of the hollow plug.

[0012] The movable cylinder slides inside the bushing, and the outer end of the hollow plug extends into the bushing.

[0013] Preferably, the bushing includes a bushing rotatably connected to the intermediate cylinder by a bearing and a limiting cylinder provided at the outer end of the bushing, and the inner wall of the bushing is provided with a sliding protrusion.

[0014] The surface of the movable cylinder is provided with a sliding groove, and the sliding protrusion slides into the corresponding sliding groove;

[0015] The inner end of the connecting rod is provided with connecting ear plates at equal intervals, and the connecting ear plates are provided with first inclined grooves. The end of the first push rod that extends into the hollow plug is provided with a first pin, and the first pin slides in the corresponding first inclined groove.

[0016] Preferably, the quick-release connection assembly includes an H-shaped lifting seat that slides in the middle of the U-shaped support, a slide block that slides in the rectangular through groove in the middle of the H-shaped lifting seat, an L-shaped frame fixed to the inner end of the slide block, a second top rod connected to the slide block, and a support seat that is fixed after the upper end of the second top rod extends out of the H-shaped lifting seat.

[0017] Preferably, the upper end of the slide block is provided with a groove in the middle, a second inclined groove is provided on the side wall of the groove, and a second pin is provided at the bottom of the second push rod, the second pin being slidably connected in the corresponding second inclined groove.

[0018] Preferably, the top of the H-shaped lifting seat is provided with a return spring sleeved on the outside of the second top rod.

[0019] Preferably, the top of the L-shaped frame is provided with a U-shaped insert tooth, and the outer end surface of the connecting rod is provided with a slot, into which the U-shaped insert tooth is inserted.

[0020] Preferably, an electric cylinder is installed at the bottom of the middle part of the U-shaped support, and the top of the piston rod at the output end of the electric cylinder is connected to the bottom of the H-shaped lifting seat.

[0021] Preferably, a vertical groove is provided on the middle side wall of the U-shaped support, and both ends of the support are slidably connected to the vertical groove. A placement groove for placing the connecting rod is provided at the upper end of the support. A limit seat is fixed to the top of the support with screws, and the lower middle part of the limit seat extends into the placement groove and abuts against the connecting rod.

[0022] Preferably, a servo motor is installed on the H-shaped lifting seat at the front, and a drive gear is connected to the output end of the servo motor. An annular external gear ring is provided on the outer side of the annular end cover at the front, and the drive gear meshes with the lower part of the annular external gear ring.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention uses a lightweight hollow cylinder as a leveling carrier, which reduces the weight by more than 60% compared with the traditional solid cylinder, and the power of the drive motor can be reduced to less than 0.5kW, reducing energy consumption by 60%; at the same time, the rolling friction between the roller and the inner wall of the hollow cylinder further reduces the rotational resistance, making the rotational speed fluctuation of the lightweight hollow cylinder ≤±2r / min, and the rotation is more stable.

[0024] The connecting support assembly uses a multi-point support structure of "first top rod + roller" to form a uniform radial support force on the inner wall of the lightweight hollow cylinder; the roller closely abuts against the inner wall of the lightweight hollow cylinder to form a multi-point uniform support, effectively resisting centrifugal force and leveling load, avoiding deformation of the lightweight hollow cylinder, improving the leveling accuracy to ±0.05mm, accurately preserving the design depth of the texture, making the texture recesses regular and three-dimensional, and reducing the defect rate of tiles.

[0025] By utilizing the weight of the hollow leveling component and the synergistic effect of the connecting support components, the two sets of symmetrical support structures automatically position the leveling component in the middle of the two sets of U-shaped supports through the support force of the rollers and the tension of the connecting rods. No manual calibration is required, and the positioning time is shortened from 30 minutes to less than 1 minute. Moreover, the coaxiality error is ≤0.2mm, significantly improving the consistency of the pattern of the same batch of tiles and greatly reducing the defect rate.

[0026] With the quick connection method of "U-shaped insert + slot" and the automatic reset function of the reset spring, the replacement of the hollow scraper component can be completed by simply lifting the component. The whole process takes ≤1 minute, which improves efficiency compared to the traditional method. Moreover, no professional tools or personnel are required. Ordinary operators can complete the operation, reducing the maintenance threshold and downtime. Attached Figure Description

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] Please see Figure 1-20 The present invention provides a technical solution:

[0059] Example 1: A processing and leveling mechanism for textured ceramic tiles, including a base 1, and a conveyor belt 2 for transporting ceramic tile blanks 3 is provided inside the base 1.

[0060] The upper end of the base 1 is provided with two sets of U-shaped supports 7 symmetrically arranged in front and back, and a hollow scraping component 6 is provided between the two sets of U-shaped supports 7.

[0061] The hollow leveling component 6 includes a lightweight hollow cylinder 601 (the hollow design of the lightweight hollow cylinder 601 controls the weight to 5-8kg), raised scrapers 602 on the surface of the lightweight hollow cylinder 601, annular end caps 603 fixed at both ends of the lightweight hollow cylinder 601 by countersunk screws 606, and an intermediate cylinder 605 centrally connected to the inner end of the annular end caps 603. The intermediate cylinder 605 extends into the lightweight hollow cylinder 601. For processing tiles with special textures such as wood grain, the texture needs to be processed into the body during the semi-finished product sample preparation process. Different textures of tiles are mainly due to the different scrapers (roller-shaped) of the scraper dryer. Different scrapers produce tiles with different textures. In this embodiment, adjacent raised scrapers 602 are tightly fitted together to ensure continuity and form a smooth surface. The corresponding leveled product is shown in the attached figure. Figure 19 As shown, the entire blank is scraped flat, the product surface is smooth, and the depressions are irregular travertine structures.

[0062] The hollow scraping component 6 has a connecting support component 9 that is symmetrically rotated front and rear inside.

[0063] The connecting support assembly 9 includes a bushing rotatably connected inside the intermediate cylinder 605, a movable cylinder 903 integrally formed on the connecting rod 901, a hollow plug 905 screwed to the inner end of the bushing, a first push rod 912 equally spaced on the inner end of the connecting rod 901, and a roller 906 movably connected to one end of the first push rod 912 extending out of the hollow plug 905.

[0064] The movable cylinder 903 is slidably connected to the inside of the bushing, and the outer end of the hollow plug 905 extends into the bushing.

[0065] The bushing includes a bushing 907 rotatably connected to the intermediate cylinder 605 by a bearing 914 and a limiting cylinder 908 provided at the outer end of the bushing 907. The inner wall of the bushing 907 is provided with a sliding protrusion 909.

[0066] The surface of the movable cylinder 903 is provided with a sliding groove 904, and the sliding protrusion 909 slides into the corresponding sliding groove 904;

[0067] Connecting lugs 910 are provided at equal intervals on the inner end of the connecting rod 901. A first inclined groove 911 is provided on the connecting lug 910. A first pin 913 is provided at one end of the first push rod 912 that extends into the hollow plug 905. The first pin 913 slides in the corresponding first inclined groove 911.

[0068] The U-shaped support 7 is equipped with a quick-release connecting assembly 4 that can be raised and lowered; the quick-release connecting assembly 4 includes an H-shaped lifting seat 401 that slides in the middle of the U-shaped support 7, a slide seat 414 that slides in the rectangular through groove 409 in the middle of the H-shaped lifting seat 401, an L-shaped frame 407 fixed to the inner end of the slide seat 414, a second push rod 413 connected to the slide seat 414, and a support seat 405 that is fixed after the upper end of the second push rod 413 extends out of the H-shaped lifting seat 401.

[0069] The upper middle part of the slide block 414 is provided with a groove 415, and a second inclined groove 416 is provided on the side wall of the groove 415. The bottom of the second push rod 413 is provided with a second pin 412, and the second pin 412 is slidably connected in the corresponding second inclined groove 416.

[0070] The top of the H-shaped lifting seat 401 is provided with a return spring 410 that is sleeved on the outside of the second top rod 413.

[0071] The top of the L-shaped frame 407 is provided with a U-shaped insert tooth, and the outer end surface of the connecting rod 901 is provided with a slot 902, into which the U-shaped insert tooth is inserted.

[0072] The connecting rod 901 of the connecting support component 9 extends out of the hollow scraping component 6 and connects to the quick-release connecting component 4;

[0073] When the hollow leveling component 6 is placed on the quick-release connecting component 4, the quick-release connecting component 4 tightens the connecting rod 901 under the action of the hollow leveling component 6's own weight, so that the inner end of the connecting support component 9 is supported on the inner wall of the hollow leveling component 6, and the hollow leveling component 6 is centered between the two sets of U-shaped supports 7.

[0074] The lightweight hollow cylinder 601 features a hollow design (weighing only 5-8 kg), significantly reducing weight compared to traditional solid structures, but also resulting in a slight decrease in structural strength. The roller 906 is designed to closely abut against the inner wall of the lightweight hollow cylinder 601, forming a uniform radial support force through multi-point support (equally spaced first push rods 912 and rollers 906). This effectively resists the centrifugal force generated during the rotation of the lightweight hollow cylinder 601 and the radial load during leveling operations, preventing deformation due to stress from affecting leveling accuracy. This support method makes the application of thin-walled hollow structures possible, ensuring structural stability while achieving lightweight design.

[0075] The roller 906 makes rolling friction contact with the inner wall of the lightweight hollow cylinder 601, with a coefficient of friction much lower than that of sliding friction. When the lightweight hollow cylinder 601 rotates under the drive of the servo motor 5, the roller 906 can roll freely along the inner wall, reducing resistance to the cylinder body. This low-resistance characteristic, combined with the lightweight design, significantly reduces the load on the drive motor 5, while avoiding vibration and jumping that may be caused by sliding friction. This allows the lightweight hollow cylinder 601 to maintain a uniform and stable rotation speed (speed fluctuation ≤ ±2r / min), ensuring a leveling accuracy (±0.05mm).

[0076] The centered installation ensures that the axis of the lightweight hollow cylinder 601 is perpendicular to the transport direction of the conveyor belt 2 and is directly above it, guaranteeing that the scraping trajectory of the raised scraper 602 on the surface of the tile body 3 is symmetrically distributed. When the tile body 3 passes under the hollow leveling component 6, the scraping depth and force on both sides remain consistent (coaxiality error ≤ 0.2mm), effectively avoiding the problem of scraping too deep or too shallow on one side due to offset, ensuring the consistency and regularity of the tile surface texture, and giving the texture a uniform, regular depression and a strong three-dimensional effect.

[0077] The centrally mounted hollow leveling assembly 6 distributes its weight and working load evenly across the two sets of U-shaped supports 7 and quick-release connecting components 4, preventing deformation or accelerated wear on one side due to excessive force. Especially when the servo motor 5 drives the hollow leveling assembly 6 to rotate at high speed (150-300 r / min), the balanced force reduces vibration and noise, decreases wear on the drive gear 8 and the annular external gear ring 604, and extends the service life of the entire transmission system.

[0078] The hollow leveling component 6 achieves automatic centering through its own weight and the synergistic effect of the connecting support component 9, eliminating the need for complex manual calibration or sensor positioning. This self-centering design allows operators to simply place the leveling component on the quick-release connecting component 4 during installation or replacement, and the structure's own mechanical balance will achieve precise positioning, greatly simplifying the adjustment process, reducing operational difficulty, and improving equipment changeover efficiency (changeover time ≤ 1 minute).

[0079] An electric cylinder 402 is installed at the bottom of the middle part of the U-shaped support 7, and the top of the piston rod 408 at the output end of the electric cylinder 402 is connected to the bottom of the H-shaped lifting seat 401.

[0080] Start the electric cylinder 402 at the bottom of the U-shaped support 7 (the electric cylinder 402 is connected to the PLC). The piston rod 408 at the output end of the electric cylinder 402 extends or retracts upward or downward (extension accuracy ±0.1mm), which drives the H-shaped lifting seat 401 fixed thereto to slide along the vertical direction of the U-shaped support 7.

[0081] The H-shaped lifting seat 401 is the core support of the quick-release connecting component 4. Its lifting will simultaneously drive the slide 414, L-shaped frame 407, support seat 405 and connecting support component 9 to lift as a whole.

[0082] When the distance between the protruding scraper 602 of the hollow leveling component 6 and the surface of the conveyor belt 2 is adapted to the thickness of the ceramic tile body 3 (usually leaving a leveling allowance of 0.5 to 1 mm), the electric cylinder 402 is turned off. The H-shaped lifting seat 401 maintains a high degree of stability through the self-locking function of the electric cylinder 402, preventing it from sinking during the leveling process.

[0083] A vertical groove 701 is provided on the middle side wall of the U-shaped support 7. The two ends of the support 405 are slidably connected to the vertical groove 701. The upper end of the support 405 is provided with a placement groove 411 for placing the connecting rod 901. The top of the support 405 is fixed with a limit seat 406 by screws. The lower middle part of the limit seat 406 extends into the placement groove 411 and abuts against the connecting rod 901.

[0084] A servo motor 5 is installed on the H-shaped lifting seat 401 at the front. The output end of the servo motor 5 is connected to a drive gear 8. An annular external gear ring 604 is provided on the outer side of the annular end cover 603 at the front. The drive gear 8 meshes with the lower part of the annular external gear ring 604.

[0085] Power transmission: Start the servo motor 5 on the front H-shaped lifting seat 401 (servo motor 5 is connected to PLC). The drive gear 8 at the output end of the servo motor 5 meshes with the annular external gear ring 604 on the outer side of the annular end cover 603 of the hollow scraping component 6, driving the lightweight hollow cylinder 601 to rotate at a uniform speed (the speed can be adjusted according to the material of the ceramic tile: 50-100 r / min for soft ceramic tile and 150-300 r / min for hard ceramic tile).

[0086] Note that when the lightweight hollow cylinder 601 rotates, the connecting support assembly 9 is stationary. The rollers 906 on the connecting support assembly 9 will roll relative to the inner wall of the lightweight hollow cylinder 601. That is, when the lightweight hollow cylinder 601 rotates, the connecting support assembly 9 can still provide stable support for the lightweight hollow cylinder 601.

[0087] Smoothing is achieved by: the raised scraper 602 on the surface of the lightweight hollow cylinder 601 rotates with the cylinder body and contacts the surface of the tile body 3. The blade of the raised scraper 602 conforms to the outline of the tile pattern and scrapes off the raised part on the surface of the tile body 3 by rotating and cutting, while retaining the design depth of the pattern (smoothing accuracy ±0.05mm), so that the pattern has regular depressions and a strong three-dimensional effect.

[0088] Example 2: The main difference from Example 1 lies in the placement of the raised scraper 602. For processing tiles with special textures such as wood grain, the texture needs to be created on the tile body during the semi-finished product preparation process. Different textures are primarily achieved by using different scrapers (roller-shaped) on the drying machine. Different scrapers result in tiles with different textures. In this Example 2, as shown in the attached manual... Figure 18 As shown, in this embodiment, there is a gap between adjacent raised scrapers 602, and the gap distribution is controlled to be between 1 and 3 mm. The scraper surface has a ribbed structure to adapt to different product leveling methods. The corresponding leveled products are shown in the attached figure. Figure 20 As shown, the product surface has regular depressions, giving it a strong three-dimensional effect.

[0089] Specifically, in use, the front and rear connecting support components 9 are assembled with the hollow leveling component 6 to form a structure as follows: Figure 8 The whole as shown;

[0090] Then, a crane was used to lift the hollow leveling component 6 and place it downwards onto the quick-release connecting component 4;

[0091] Align the U-shaped inserts on the top of the L-shaped frame 407 with the slots 902 on the surface of the connecting rod 901 to initially limit the radial displacement of the connecting rod 901. Continue to lower the hollow scraping assembly 6. The connecting rods 901 of the connecting support assemblies 9 at both ends of the hollow scraping assembly 6 are placed in the placement slots 411 of the support base 405 of the quick-release connecting assembly 4.

[0092] The gravity of the hollow scraping component 6 and the connecting support component 9 acts on the support base 405 of the quick-release connecting component 4. The support base 405 moves downward relative to the H-shaped lifting base 401. At this time, the return spring 410 is gradually compressed, and the second pin 412 at the bottom of the second push rod 413 slides downward along the second inclined groove 416, so that the slide 414 slides relative to the H-shaped lifting base 401 along the rectangular through groove 409. At this time, the L-shaped frame 407 fixed on the inner end of the slide 414 gradually pulls the connecting rod 901 outward. At this time, the moving cylinder 903 on the connecting rod 901 moves outward relative to the bushing.

[0093] The connecting lug 910 at the inner end of the connecting rod 901 also moves, causing the first pin 913 on the first push rod 912 to move inward along the corresponding first inclined groove 911 until the first push rod 912 extends further out of the hollow plug 905, and causing the roller 906 of the connecting support assembly 9 to abut tightly against the inner wall of the lightweight hollow cylinder 601 of the hollow scraping assembly 6, and the drive gear 8 to mesh with the lower part of the annular external gear ring 604.

[0094] The two sets of symmetrically arranged connecting support components 9 automatically position the hollow scraping component 6 in the middle of the two sets of U-shaped supports 7 through the supporting force of the roller 906 and the tension of the connecting rod 901, with a coaxiality error of ≤0.2mm, avoiding scraping too deep or too shallow on one side when scraping.

[0095] Subsequently, the limiting seat 406 is fixed to the top of the support seat 405 with screws. The lower end of the limiting seat 406 extends into the placement groove 411 and abuts against the connecting rod 901, further restricting the connecting rod 901 and preventing the connecting rod 901 from popping out of the placement groove 411.

[0096] As the roller 906 presses tightly against the inner wall of the lightweight hollow cylinder 601, and under the gravity of the hollow leveling assembly 6 and the connecting support assembly 9, the hollow leveling assembly 6, the connecting support assembly 9 and the quick-release connecting assembly 4 are in a relatively stationary state. At this time, since the U-shaped inserts on the top of the L-shaped frame 407 are aligned and inserted into the slots 902 on the surface of the connecting rod 901, the axial movement of the connecting rod 901 can be effectively prevented, ensuring stable transmission when the hollow leveling assembly 6 rotates.

[0097] When the raised scraper 602 wears out or needs to be adapted to tiles with different textures, the hollow leveling component 6 can be quickly disassembled through the quick-release connecting component 4, as follows:

[0098] Remove the limiting seat 406 from the top of the support seat 405;

[0099] Then, the hollow leveling component 6 is lifted vertically upwards by a crane. At this time, the U-shaped insert at the top of the L-shaped frame 407 gradually disengages from the slot 902 on the surface of the connecting rod 901. The support seat 405 is no longer subjected to the gravity of the hollow leveling component 6. The return spring 410 gradually lifts the support seat 405, causing the second pin 412 at the bottom of the second push rod 413 to slide upwards and reset along the second inclined groove 416. The slide 414 drives the L-shaped frame 407 fixed at its inner end to gradually push the connecting rod 901 inwards. At this time, the moving cylinder 903 on the connecting rod 901 moves inwards relative to the bushing, and the connecting ear plate 910 at the inner end of the connecting rod 901 also moves together, causing the first pin 913 on the first push rod 912 to move and reset along the corresponding first inclined groove 911 until the first push rod 912 further retracts into the hollow plug 905, and the roller 906 disengages from the inner wall of the lightweight hollow cylinder 601.

[0100] Disassembly is complete once the hollow leveling component 6 is removed (the entire process requires no tools and takes ≤1 minute). After replacing the new hollow leveling component 6, repeat the above installation steps for the hollow leveling component 6 to achieve quick reinstallation.

[0101] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
